Hi Chrisx,
There are three types of recalls:
• Class I - a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death.
• Class II - a situation in which use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.
• Class III - a situation in which use of, or exposure to, a violative product is not likely to cause adverse health consequences.
Under 21 CFR 806, manufacturers and importers need not report events categorized as class III recalls under 21 CFR §7; only record keeping requirements would apply.
So, if the complaint is about a situation that is not likely to cause adverse health consequences (e.g. minor issue, routine service, normal ware) I do not think the agency will come after you or consider this as recall.
Keep in mind that your internal records - complaint investigation, risk management, etc. need to support you assessment.
Cheers,
Shimon
